>GTK's behavior (no clipping) is a consequence of its
attempts to conserve X resources. Label widgets (among
others) don't get their own X window - they just draw their
contents on their parent's window. While it might be possible
to have clipping occur by setting the clip mask before
drawing the text, this would probably cause a substantial
performance penalty.</P
><P
>Its possible that, in the long term, the best solution
to such problems might be just to change gtk to give labels X
windows. A short term workaround is to put the label widget
inside another widget that does get its own window - one
possible candidate would be the viewport widget.</P
